Doubts raised about CRISPR gene-editing study in human embryos

For the first time epigenetic inheritance is observed at the molecular level in Drosophila: zygote needs mother's histone methyltransferase to properly regulate the expression of developmental genes. [Science, 2017]

We are more than the sum of our genes. Epigenetic mechanisms modulated by environmental cues such as diet, disease or lifestyle take a major role in regulating the DNA by switching genes on and off. It has been long debated .

Two groups of scientists successfully applied a personalized immunotherapy approach against melanoma. By sequencing tumor exomes they first identified the repertoire of neoantigenes specific to each patient. Then, they devised RNA- or peptide-based vaccines to target 10 to 20 neoantigenes at a time either with or without PD-1 inhibitor. Results look very promising [both papers were published in Nature, 2017]

Personalized cancer vaccines show glimmers of success - Treatments tailored to a person's individual cancer mutations train immune system to attack tumours.

Entosis - a type of cellular cannibalism - is widespread in tumors. It usually depends on detachment from extracellular matrix. Here researchers report a new mechanism of entosis which is triggered by a faulty cell division [eLife, 2017]

Cell cannibalism in tumour samples has been observed for over a century, yet this unusual behaviour is not well studied. New research led by scientists at the Babraham Institute, Cambridge reveals a new mechanism driving .

RNase III called Drosha, which is involved in miRNA processing in the eukaryotic nucleus, first evolved as antiviral protein targeting RNA dependent RNA polymerase and viral replication intermediates. [Nature, 2017]

Researchers identify one of the cases of immune checkpoint blockade failure: the cytotoxic T cell exhaustion. By blocking de novo DNA methylation in activated CD8 T cells they were able to restore their effector functions despite chronic stimulation during a persistent viral infection. Similar approach worked in cancer (both experiments were done on mouse models) [Cell, 2017]

Altering DNA methylation may reverse T-cell exhaustion, improve checkpoint blockade

Scientists are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle's protein shell. This work could benefit research in bioenergy and pathogenesis, and it could lead to new methods of bioengineering bacteria for beneficial purposes [Science, 2017]

The novel PTEN-dependent tumor suppression pathway is discovered. It is based on the ability of PTEN to induce Ca-dependent apoptosis. The drug, geranylgeranyltransferase inhibitor GGTI-2418 is restoring the normal phenotype in defective PTEN cancer cell making them sensitive to photodynamic therapy. [Nature, 2017]

The drug, geranylgeranyltransferase inhibitor suppresses a new defective PTEN cancer pathway, researchers have discovered.
